Pedestrian Safety Device Wind Diverter (PSDWD-10)

ABSTRACT

The invention provided is a Pedestrian Safety Device Wind Diverter for the Stop sings attached to transportation vehicles hereto referred to as “PSDWD-10”. The PSDWD-10 is made of polycarbonate plastic prepared according to the above process. In some embodiments of the invention, the polycarbonate plastic material is reinforced by layers of polycarbonate plastic as designed to strengthen the diverter as wind force and turbulence increase around the various angles of the PSDWD.

BACKGROUND OF THE INVENTION

Wind is frequently distributed by various types of diverters, bothhorizontal and vertical, in which the wind is discharged and builds upbehind the various points from one end to the other, for example.Without restrictions thereto, wind is discharged forcing various objectsto vibrate adding additional pressure on the mechanism designed to holdthe object in place. Particularly when the speed of the moving object isincreased the wind may gather behind the object forcing it to waiverback and forth from the object for which it is attached. Whereby thePSDWD-10 widget is particularly designed to not only substantiallyreduce the collecting of the wind behind PSDWD but to also limit PSDWDfrom rocking back and forth thereby stabilizing the object and aiding inthe prevention of PSDWD from becoming a potential hazard to others onthe road and the safe transportation of children. The PSDWD-10 widget isdesigned to be retro fitted to already existing objects and included asa attachment to new devices/objected.

It has proposed that, particularly when the PSDWD-10 widget is combinedwith already existing objects, for example, the useful life of theobject is lengthened and the safety rating is increased when relative tostrong wind is blowing against the PSDWD, the wind from both thehorizontal and vertical perspective is discharged along the PSDWD awaypreventing the wind from gathering behind PSDWD and thus making PSDWDsafer. One type of diverter having general characteristics therein thewind will be discharged at the upper ends thereof is illustrated in U.S.Pat. Nos. 2,377,760, 3,220,539, June 1945, November 1965. Although thediverter in PSDWD patent is readily subject to being blown by a passingwind. The problem of redirecting the wind when discharging from thePSDWD to which the PSDWD-10 device is attached is that the intendedobject may come in various prior shapes, and structures, not only in thecombined state but as a retro-fit device for diverting the wind aroundPSDWD. For example, placing a PSDWD-10 device around PSDWD to dischargethe wind would accomplish the same desired manner comprises in thesubject matter of a PSDWD-10 device shown as a horizontal and/orvertical discharge shield therein a shield means included in thedischarge end of the PSDWD to achieve desired re-directing of thedischarge wind.

Although the aforementioned prior devices include certain types ofshields associated with the discharge end of wind and the like in whichthe PSDWD-10 device is employed, none of them seems to be suitablyadapted to solve the problem of effectively or simply shielding winddischarge from the horizontal and/or vertical passing wind. Therefore,it is the object of the present invention to provide such a wind guardor shield which particularly is adapted to be mounted adjacent the upperend of PSDWD having the PSDWD type therein, details of which are setforth hereinafter.

SUMMARY OF THE INVENTION

t is the principal object of the present invention to provide awind-guard or shield in the form of a PSDWD-10 device which attaches tothe wall of greater diameter than that of the diverter and mounted onthe upper end of PSDWD wall in a manner to project upwardly downwardlyand around PSDWD diverter a predetermined distance, PSDWD wall beingradically spaced from the upper end of the diverter so as to provide anannular discharge space through which wind may flow by gravity whilebeing shielded from contact by wind due to the shaking and rockingeffect of the portion of the PSDWD wall which projects beyond the upperend of PSDWD device.

It is another object of the invention to support and extend the life ofPSDWD upon which the PSDWD-10 device be retro-fitted and/or included asa attachment of PSDWD by means which permit adjustable movement of PSDWDdiverter relative to the upper end of PSDWD and thereby adapt thestructure to accommodate different wind discharge speed as well as toprovide effective shielding of the discharge wind of different amountsand velocities.

It is a further object of the invention to support PSDWDPSDWD-10 deviceby relatively simple bracket means that offer minimum obstruction to thepassage of the wind through the annular space around PSDWD, PSDWDadjustment of PSDWD being accomplished by simple means and PSDWDadjustment being stabilized by suitable pre-existing clamping bolts andthe like.

It is still another object of the invention to adapt PSDWDPSDWD-10device to the upper end of PSDWD in which the objects limited distancebeyond the upper end of the PSDWD-10 device and a suitable bearingbracket is attached to PSDWD upper end of the PSDWD to receive the upperend of the PSDWD-10 device of PSDWD and, ancillary to the foregoingobject of the invention, it is a further object to utilize thesupporting brackets for the object wall in circumferentially spacedrelationship to the bearing bracket so as to provide minimum obstructionto the passage of wind between PSDWD-10 device and PSDWD wall.

One further object of the invention is to adapt the object wallshielding means to the upper end of a object which is inclined a limiteddistance to the vertical and utilize the various brackets for thebearing and support of the object wall in locations nearest the verticalwall to which the PSDWD-10 device is attached, whereby the portion ofthe annular space between the PSDWD wall and upper end of the PSDWD-10device which is furthest from PSDWD vertical wall will be substantiallyfree of brackets and there for unobstructed and readily capable offreely discharging wind between PSDWD unobstructed portion of the objectwall and the upper end of PSDWD.

One further object of the invention is to adapt the object wallpreventing it from becoming detached from the supporting object wallwhereby the portion of the PSDWD will be unsupported and there forbecome a flying projectile endangering the lives of the others. Detailsof the foregoing objects and of the invention, as well as other objectsthereof, are set forth in the following specification and illustrated inthe accompanying drawings comprising a part thereof.

DETAILED DESCRIPTION

The PSDWD-10 device for PSDWD wind distributor which comprises thepresent invention may be employed in a variety of situations fordistributing wind from PSDWDPSDWD-10 device, for example, to areceptacle to receive the same. As indicated hereinabove, there isparticular need for a PSDWD-10 device of such type in regard to a winddistributor for the safe transportation of PSDWD to prevent the PSDWDfrom becoming a road hazard or flying projectile in the case of PSDWD asemployed on PSDWD such as shown in FIG. 1a , in which the PSDWD-10device, which as seen in FIG. 1 and therein extends upwardly from alower portion of PSDWD FIG. 1a around the PSDWD.

It is conventional that the upper end of the PSDWD-10 device FIG. 2 bedisposed either substantially at a level with the upper rim of thePSDWD-10 device FIG. 1a or at a higher elevation than PSDWD rim in orderthat wind, when discharged from the upper end of the PSDWD-10 device,will be able to move around the PSDWD-10 device FIG. 1 substantially tothe full length and depth of the FIG. 1. The PSDWD-10 device and evendispose the central part of the PSDWD-10 device at a higher level thanthe rim of the FIG. 1, thereby constituting a fully engaged PSDWD-10device and fully discharged wind around PSDWD device.

It will be understood that the PSDWD-10 device FIG. 1 is designed tomove the wind in by a conventional means, not shown, but employed innatural movement of by wind types not shown in exemplary manner inFIG. 1. The PSDWD-10 device is designed to redirect the direction of thewind from the PSDWD mechanism in the lower portion of the \ PSDWD objectFIG. 1a , to the upper/lower end of the PSDWD-10 device FIG. 1 fordischarge of the same around the PSDWD FIG. 1 a.

Further, as shown in FIG. 4, it is conventional in mounting PSDWD-10devices FIG. 1, attached to PSDWD. For example, in FIG. 4, the verticalis indicated by an exemplary axis FIG. 1a , and it will be seen that theaxis FIG. 1, is at an inclined angle thereto indicated by an arc Awhich, for example, may be of the order of approximately 0.064 degree.Such designation is not intended to be restrictive however but merelyexemplary. Other appropriate angles may be used.

Referring particularly to FIG. 3, it will be seen that the upper end ofthe PSDWD-10 device FIG. 1 is provided with a preferably axiallyadjustable PSDWD wall FIG. 2 which comprises a PSDWD-10 device or shieldwhich minimizes the possibility of the threshed wind, when dischargedfrom the upper end FIG. 3 of PSDWD-10 device FIG. 1.

It will be seen from FIG. 4 that the object wall is of greater diameterthan that of the PSDWD-10 device FIG. 1 and both of PSDWD elementspreferably are fitted. The difference in diameters between the twoelements is sufficient to provide a substantially annular space FIG. 4between the inner surface of the PSDWD wall FIG. 2 and the outer surfaceof the upper end portion of the PSDWD-10 device FIG. 3.

Also as illustrated in FIG. 4, it will be seen that as the wind blows ina direction toward the PSDWD-10 device FIG. 1 the diverter will directthe wind upward FIG. 2 thereof, the wind would then be discharged in theform of an exemplary stream and fall by gravity from the lower end ofthe PSDWD wall FIG. 1. From FIG. 4, it also will be seen that in view ofthe fact that the upper end of the PSDWD wall FIG. 1a extendssubstantially beyond the upper end FIG. 1 of PSDWD-10 device FIG. 1,there is little if any possibility for wind passing through/under PSDWDwall to carry any of the wind with it beyond the boundary of thePSDWD-10 device FIG. 1.

For purposes of providing effective discharge of wind from the upper endof the PSDWD FIG. 1, it is preferred that the upper end of the PSDWD-10device FIG. 1 extend beyond the upper end of PSDWD FIG. 3, as also shownin FIG. 4, PSDWD upper end of the PSDWD terminating in a projecting endof the 0.064 degrees of the PSDWD.

Further, it will be noted that the PSDWD FIG. 1 which is secured to thewall of PSDWD FIG. 2 is nearest the vertical wall FIG. 1a , whereby thediametrically opposite portion of the annular space FIG. 1, from that inwhich the attached wall of PSDWD FIG. 1a is located, is substantiallyfree of obstruction with respect to wind being discharged into and fromPSDWD angular space, as exemplified by the stream in FIG. 4.

For purposes of supporting the PSDWD wall FIG. 2 which comprises thePSDWD with respect to the PSDWD-10 device FIG. 1, attention is directedto FIGS. 2 and 3 in which it will be seen that, preferably, a pair ofsupporting brackets FIG. 1a are provided, preferably at diametricallyopposite sides of PSDWD-10 device FIG. 1 and PSDWD wall. The bracketsFIG. 2 may be formed from suitable strip pliable foam of appropriatewidth and thickness, such as PVC Foam Board, and one leg FIG. 1, of eachbracket is secured fixedly against the inner surface of the PSDWD wallFIG. 1a , such as by plastic welding or otherwise. Each bracket FIG. 1,also is provided with an offset leg FIG. 2, of suitable length to permita limited range of axial adjustment of the tubular wall FIG. 1a ,relative to the upper end of PSDWD-10 device FIG. 1a . Two exemplaryadjusted positions of the PSDWD wall FIG. 1a , are illustrated in FIG.4, one of these being in full lines and a lower position being indicatedin phantom.

To permit such axial adjustment of the PSDWD wall FIG. 1a , with respectto PSDWD-10 device FIG. 1, the offset legs FIG. 2, thereof are receivedin suitable socket members FIG. 2, which are of limited length butadequate to provide effective support for the PSDWD wall FIG. 1a , in adesired adjusted position. The socket members FIG. 2, in end view asseen in FIG. 1, are substantially U-shaped and the length of the legs ofPSDWD brackets, which are firmly secured to the outer surface ofPSDWD-10 device FIG. 4, by any suitable means, are relatively short butadequate to provide a space capable of readily receiving the oppositelegs FIG. 2, of the brackets FIG. 1, for ready slide-able movementrelative to PSDWD socket members.

A desired adjusted position of the PSDWD wall FIG. 2 with respect to theupper end of PSDWD-10 device FIG. 1, is maintained by securing means ofsuitable type. The means specifically shown in FIGS. 2 and 3 comprisesan inexpensive manufactured expedient comprising a nut(s) FIG. 2,affixed to the outer surface of the socket member and a securingbolt/suitable means is thread ably received through PSDWD nut andextends through an aligned hole in the outer wall of socket member FIG.2, in order that the inner end of bolt FIG. 2, may engage in clampingmanner the offset leg FIG. 2, of each bracket FIG. 1. After PSDWD bolts12+ have been tightened into clamping relationship with the legs FIG. 2,securing foam is injected upon the bolt FIG. 2, against the fixed nutFIG. 4.

It will be seen from FIG. 2 that the supporting brackets are preferablydisposed in diametrically opposed positions with respect to the axis ofthe PSDWD FIG. 1, and bearing bracket FIG. 2 is disposedcircumferentially midway between the supporting brackets FIG. 3, wherebyit will be seen from FIG. 2 that the lower half of the annular spaceFIG. 2, between PSDWD wall FIG. 3, and PSDWD-10 device FIG. 1a , is freeof obstruction by any of the brackets. In view of this, referring toFIG. 4, it will be seen that in the preferred construction of the PSDWDcomprising the present invention, and especially when the PSDWD-10device FIG. 1, is mounted at an incline with respect to the verticalsuch as axis FIG. 4, PSDWD tube is arranged so that the bearing bracketFIG. 2, is positioned nearest the axis FIG. 3, and the supportingbrackets FIG. 4, respectively are disposed at 90.degree. theretorelative to the axis of PSDWD FIG. 1a , whereby PSDWD relativelyunobstructed half circumference of the annular space FIG. 1, referred toabove, which is between the PSDWD-10 device FIG. 1, and tubular wallFIG. 1a , is disposed farthest from the vertical axis FIG. 1, therebyproviding PSDWD unobstructed portion of PSDWD angular space in alocation where it is most advantageous for purposes of permitting readydischarge of the stream of wind FIG. 1, from the upper end of thePSDWD-10 device FIG. 2, and permit the same to fall by gravity from thelower end of PSDWD wall FIG. 1a , as shown in exemplary manner in FIG.4.

It readily can be visualized that, depending upon the volume of windbeing discharged from the device, for example, and delivered to thePSDWD-10 device, as well as the rate of operation of the PSDWD FIG. 1a ,it may be desirable from time to time under certain circumstances toreplace the PSDWD-10 device FIG. 1, and this may be readily accomplishedby loosening the securing plastic (not shown) FIG. 2, and locknuts FIG.4, re-moving the PSDWD FIG. 1, in the desired axial direction, and thenreplacing it by re-clamping the supporting brackets FIG. 4, with respectto the socket members and re-applying new securing plastic strips (notshown).
